Cabinet structure
The basic structure of the switchgear cabinet is composed of C-shaped profiles. C profile is made by bending steel plate with E = 25mm as module
mounting hole. All cabinet frames and inner partitions are galvanized and purified. The door panels and side panels are sprayed with high-voltage static
electricity.

Switchgear type

◆ Power distribution center cabinet (PC): Emax, MT, 3WN, AH, ME and other circuit breakers can be used.
◆ Motor Control Center Cabinet (MCC): Assembled by large and small drawers, the main switch of each circuit adopts high-breaking plastic case circuit
breaker or rotary load switch with fuse. Power factor automatic compensation cabinet (with manual, automatic and remote power factor compensation
devices)
